Problems solved by technology

However, when two devices stand facing each other, usually the two devices cannot emit beams at the same time, because when one device scans, if the other emits beams, it will generate a signal on the detector of the normally scanning one, so Can't get a normal scan image

Abstract

Disclosed are a human body backscattering security inspection system and a method thereof. Let one device start scanning, and the other device does not move; when the first device scans to the second device and the beam will not directly incident on the detector of the first device, the second device starts scanning; The scanning speed of the two devices is the same, so the rays of the two devices will not directly hit the detector of the opposite device during the scanning process; after the first device scans, the second device continues to scan until the end. Compared with the scanning of two devices separately, such a scanning process shortens the time. The specific shortening time depends on how long the first device scans before the second device has no influence on it.

Description

technical field [0001] The technology relates to radiation imaging technology, in particular to a human body backscatter security inspection system and a method thereof, which can improve the scanning speed of the security inspection system. Background technique [0002] Backscatter imaging technology is one of the main technologies for human security inspection. By scanning the human body with X-ray beams and using large-area detectors to receive scattered signals, the scattered images can be obtained by corresponding the scanning position with the scattered signals during data processing. [0003] When neither the backscatter device nor the scanned person is moving, one scan can only scan the image of one side of the scanned person. If a complete security check is to be performed on the human body, the inspected person needs to turn around after scanning one side, and then scan the other side again. [0004] In order to improve the inspection efficiency, the backscatter i...
